E-Commerce Platform — Enterprise-Grade
A full-stack online store and admin system built with Next.js 15 and NestJS 11. Customers can browse products, manage carts and wishlists, checkout with multiple payment methods, and track orders and returns. Store owners get a rich admin panel for products, orders, customers, theme customization, analytics, and operational tools (inventory, coupons, loyalty, backups).
This project is a complete e-commerce solution — not just a product listing page. It separates concerns into a Next.js storefront (frontend/) and a NestJS REST API (backend/), backed by PostgreSQL and Redis, with optional Docker Compose for the full stack.
The storefront includes ~98 routes: home (v2 layout with promo grids), shop, product detail with variations, cart, multi-step checkout, customer account (orders, addresses, wishlist, returns, loyalty), blog, help center, FAQ, and static pages (shipping, policies, etc.). State is handled with Zustand (cart, compare, quick view, recently viewed). Payments use Stripe and PayPal. The UI supports i18n, multi-currency, dark mode, PWA/offline behavior, and a theme customizer (header, footer, product cards, shop layout).
The admin panel covers day-to-day store operations: dashboard with stats, product CRUD with import/export and variant generation, categories, orders and returns, customers, coupons, tax and shipping, inventory, abandoned carts, reviews, newsletter, FAQ, email templates, roles, activity logs, webhooks, backup/restore, and security audit logs.
The API exposes 180+ endpoints across 43+ NestJS modules (products, orders, cart, payments, loyalty, chat, WhatsApp/SMS integrations, metrics, etc.), with JWT auth, role-based permissions, Swagger docs, rate limiting, and Prometheus metrics. The database has 39 TypeORM entities, migrations, soft delete, and indexed queries for orders and reviews.
DevOps & quality: GitHub Actions CI, Jest unit tests, Playwright E2E smoke tests, pre-production validation scripts, health checks, and Docker deployment for Postgres, Redis, API, and frontend.
